Light used to detect quantum information stored in 100,000 nuclear quantum bits

Researchers have found a way to use light and a single electron to communicate with a cloud of quantum bits and sense their behavior, making it possible to detect a single quantum bit in a dense cloud.

Moiré patterns facilitate discovery of novel insulating phases

Materials having excess electrons are typically conductors. However, moiré patterns—interference patterns that typically arise when one object with a repetitive pattern is placed over another with a similar pattern—can suppress electrical conductivity, a study led by physicists at the University of California, Riverside, has found.

Researchers explore using light to levitate discs in the mesosphere

A team of researchers at the University of Pennsylvania has found that it is possible to levitate very thin discs in conditions that mimic the mesosphere using laser light. In their paper published in the journal Science Advances, the group describes their research involving a possible way to allow flight at very high altitudes and how well it worked.

Two-dimensional superconductivity and anisotropic transport at potassium tantalate interfaces

Unique electronic structures found at materials interfaces can allow unconventional quantum states to emerge. In a new report on Science, Changjiang Liu and a research team at the Argonne National Laboratory, University of Illinois and the Chinese Academy of Sciences detailed the discovery of superconductivity in electron gases formed at the interfaces between potassium tantalate (KTaO3) and insulating overlayers of either Europium-II oxide (EUO) or lanthanum aluminate (LaAlO3). The superconducting transition temperature approaching 2.2 K observed in this work was an order of magnitude higher than previous systems of lanthanum aluminate/strontium titanate. The critical field and current-voltage measurements indicated the two-dimensional (2-D) character of superconductivity. The team noted a spontaneous in-plane transport anisotropy in the EUO/ KTaO3 samples prior to the onset of superconductivity to suggest the emergence of a distinct 'stripe' like phase near the critical field.

New physics rules tested on quantum computer

Aalto researchers have used an IBM quantum computer to explore an overlooked area of physics, and have challenged 100-year-old notions about information at the quantum level.

Random twists of place: How quiet is quantum space-time at the Planck scale?

Citizen scientists discover companion star of APMPM J2036-4936

A low-mass companion to a distant star known as APMPM J2036-4936 has been recently detected as part of the citizen science project Backyard Worlds: Planet 9. The finding of the star, which received designation CWISE J203546.35-493611.0, was detailed in a paper published February 4 on the arXiv pre-print repository.

Large proto-cluster of galaxies discovered in the midst of clearing the cosmic fog

When the universe was about 350 million years old it was dark: there were no stars or galaxies, only neutral gas—mainly hydrogen—the residue of the Big Bang. That foggy period began to clear as atoms clumped together to form the first stars and the first quasars, causing the gas to ionize and high-energy photons to travel freely through space.

UConn astrophysicist Chiara Mingarelli is part of a team of researchers who recently published data on a hint of a signal that sent ripples of excitement through the physics community. These monumental findings are the culmination of 12 and a half years of data gathered from NANOGrav—a network of pulsars across the galaxy—all in the hopes of detecting gravitational waves.

Lunar Reconnaissance Orbiter gets an upgrade to capture new perspectives of the moon

Eleven years into its mission, the Lunar Reconnaissance Orbiter (LRO) is starting to show its age, but a recent software update promises to give the spacecraft a new lease on life. As NASA's eye in the sky over the moon, the LRO has been responsible for some of the best Lunar observations since the days of Apollo. This new upgrade will allow that legacy to continue.

Recently, the wind energy industry has been expanding rapidly, with a growing number of companies and governments investing in the use of wind turbines and other wind energy converters.

New skin patch brings us closer to wearable, all-in-one health monitor

Engineers at the University of California San Diego have developed a soft, stretchy skin patch that can be worn on the neck to continuously track blood pressure and heart rate while measuring the wearer's levels of glucose as well as lactate, alcohol or caffeine. It is the first wearable device that monitors cardiovascular signals and multiple biochemical levels in the human body at the same time.

A machine-learning approach to finding treatment options for COVID-19

When the COVID-19 pandemic struck in early 2020, doctors and researchers rushed to find effective treatments. There was little time to spare. "Making new drugs takes forever," says Caroline Uhler, a computational biologist in MIT's Department of Electrical Engineering and Computer Science and the Institute for Data, Systems and Society, and an associate member of the Broad Institute of MIT and Harvard. "Really, the only expedient option is to repurpose existing drugs."

Tools reveal critical infrastructure connections, help mitigate disasters

Major disasters, whether natural or human-caused, most often have a devastating impact on local infrastructure that can result in the interruption of humanitarian efforts and deal an economic blow to communities large and small. No matter where you are in the world, these infrastructures are intimately linked, so that the failure of one can have a cascading effect on others.

Energy poverty in Zimbabwe takes many forms but policy only looks at one

Around the world, many countries measure energy poverty by looking at income. They define energy poverty in terms of how much of a household's budget is used up by energy consumption. For example, if a household spends more than 10% of its income on domestic energy needs, it's considered energy poor.
